Python 3 - input() function
Last Updated : 07 Apr, 2025
In Python, we use the input() function to take input from the user. Whatever you enter as input, the input function converts it into a string. If you enter an integer value still input() function converts it into a string.
Python input() Function Syntax
Syntax: input(prompt)
Parameter:
- Prompt: (optional) The string that is written to standard output(usually screen) without newline.
Return: String object
How input() Function works in Python?
In this example, we are using input() function to input user data as a string in Python.
Python name = input("What is your name? ") print("Hello, " + name + "!") Output
What is your name? GFG
Hello, GFG!
input() Function in Python Examples
Taking input in Python
In this example, we are using the Python input() function to input user data as a string in Python, which takes input from the user and prints it.
Python # Taking input from the user string = input() # Output print(string)
Output
geeksforgeeks
User Input in Python
In this example, we are taking input from the user and input user data as a string in Python with a prompt and printing it.
Python # Taking input from the user name = input("Enter your name") # Output print("Hello", name) Output
Enter your name:ankit rai
Hello ankit rai
Convert User Input to a Number
In this example, we are using the Python input() function which takes input from the user in string format converting it into an integer adding 1 to the integer, and printing it.
Python # Taking input from the user as integer num = int(input("Enter a number:")) add = num + 1 # Output print(add) Output
Enter a number:15
16
Take float input in Python
In this example, we are using the Python input() function which takes input from the user in string format converts it into float adds 1 to the float, and prints it.
Python # Taking input from the user as float num =float(input("Enter number ")) add = num + 1 # output print(add) Output
Enter number 5
6.0
Python Accept List as a input From User
In this example, we are taking input from the user in string format converting it into a list, and printing it.
Python # Taking input from the user as list li =list(input("Enter number ")) # output print(li) Output
Enter number 12345
['1', '2', '3', '4', '5']
Take User Input for Tuples and Sets
In this example, we are taking input from the user in string format converting it into a tuple, and printing it.
Python # Taking input from the user as tuple num =tuple(input("Enter number ")) # output print(num) Output
Enter number 123
('1', '2', '3')
Input with a dictionary comprehension
In this example, we are taking the words separated by space to input user data as a string in Python, and we make a dictionary of the word as the key with their length as the value.
Python words_str = input("Enter a list of words, separated by spaces: ") words = {word: len(word) for word in words_str.split()} print(words) Output
Enter a list of words, separated by spaces: geeks for geeks
{'geeks': 5, 'for': 3}
